$_COOKIE

$HTTP_COOKIE_VARS [deprecated]

Description

An associative array of variables passed to the current script
via HTTP Cookies.

$HTTP_COOKIE_VARS contains the same initial
information, but is not a superglobal.
(Note that $HTTP_COOKIE_VARS and $_COOKIE
are different variables and that PHP handles them as such)

Changelog

Version

Description

4.1.0

$HTTP_COOKIE_VARS.

Examples

Example #1 $_COOKIE example

<?phpecho 'Hello ' . htmlspecialchars($_COOKIE["name"]) . '!';?>

Assuming the "name" cookie has been set earlier

The above example will output
something similar to:

Hello Hannes!

Notes

Note:

This is a 'superglobal', or
automatic global, variable. This simply means that it is available in
all scopes throughout a script. There is no need to do
global $variable; to access it within functions or methods.
